* fix(cli): first-run startup creates global config with project registered
Regression from #1781: persistUpdateChannel() created an empty global config
({ projects: {} }) before autoCreateConfig() registered the project. Dashboard
loaded this empty config - zero projects - session not found.
Two-part fix:
1. autoCreateConfig() now calls registerProjectInGlobalConfig() after creating
the local yaml, so the global config is bootstrapped with the project
before maybePromptForUpdateChannel() or startDashboard() run.
2. persistUpdateChannel() and maybePromptForUpdateChannel() early-return when
no global config exists, preventing empty-husk creation.
Fixes#1766
* fix(cli): fix type error in persistUpdateChannel and update JSDoc
